Re: That is

You write:-

"I would hope that this preflash is so weak that it would not register on a light meter very much to matter..."

That was not my experience. 'Though weak, the pre-flash triggered my Polaris flash meter 'early', so the main/taking flash was not registered by the meter at all.

To avoid pre-flash all Ex units need to be in 'M', .. AND not have 'master' showing on their screens.
